<short>Ensures that the specified object instance is freed and set to Nil</short>
<descr>
<var>FreeThenNil</var> is a procedure used to ensure that the object instance in <var>obj</var> is freed and set to Nil. If obj has been assigned, it is cast to a <var>TObject</var> instance and its Free method is called. Finally, the pointer to the address in obj is set to Nil.

<element name="GetEnumValueDef">
<short>Gets the ordinal position for an enumeration value with the specified name</short>
<descr>
<p>
<var>GetEnumValueDef</var> is an <var>Integer</var> function used to get the ordinal position in the specified enumeration type insformation for the value with the given name.
</p>
<p>
The return value contains the ordinal position in <var>TypeInfo</var> for the enumeration value with the given <var>Name</var>. GetEnumValueDef calls <var>GetEnumValue</var> to find the value in Name in the type information. If the return value is <b>-1</b>, an enumeration value with the specified name is not found in TypeInfo and the value in <var>DefaultValue</var> is used as the return value.
